Trying to help my friend get an Acekard2i. He's getting a DS in a few weeks or so, and I got him interested in the Acekard.
They don't sell them anymore. Not even the "workarounds". You can buy it from http://realhotstuff.com/ or http://www.leetmod.com/acekard-2i-cartridge-for-nintendo-dsi-ds-lite-ds-p-169.html?zenid=kv8buf6ja0foblnevhld7e7qn4.
